Seriously i don't know how to explain this

The colors are ALL messed up

So it clears up when you press escape to pause the game? D: well it looks like a very strange error. Have you tried re-seating your video card? cleaning it of dust etc.?

That looks like a hardware or driver problem.

hmmm

Fixed up re-installing the game

You pushed escape which fixed the screen corruption and showed the invisible worms.
